In animal feeding technology much attention is given to application of biologically active substances for metabolism stimulation. One of such biologically active substances is carnitine, an anabolic preparation of nonhormonal nature, cofactor in system of oxidation of fat acids. It participates in processes of acetylation at oxidation of fat acids together with acyl-CoA and other enzymes, promotes carrying over of cytoplasmatic Coa-derivatives of fat acids inside mitochondrions. It increases absorption speed from a digestive path of nutrients of forage, raises use of fat acids for the power purposes. Under its influence synthesis of triglycerides decreases and synthesis of phospho-lipids increases. Carnitine also protects cells against toxic accumulation of components of acyl-CoA of endogenic or exogenous origins, such as acylic groups of carnitine ethers which then can pass into liver for dissimilation or in kidneys for allocation in urine. Carnitine synthesis satisfies body requirements, but in the conditions of a hightened stress, high productivity, as well as in the conditions of lowered carnitine content in forage or in the conditions of the increased content of fats it should be applied as additive to diet. As a result of the realized study it was established, that the optimal quantity of carnitine application in diets for stores husbandry and fattening is dose of 50 g/t of mixed fodders. Application of carnitine in an optimum dose renders the positive impact on animal organism, promotes the increasing average daily weight gain on 5,1% (Р less than 0,001). Application of carnitine in diets of swine stores increases a slaughter yield on 2,1%, meat content per carcass - on 2,3%, a loin eye area - on 8,8%. Carnitine application in a dose 50 g/t of mixed fodders makes it possible to receive the additional profit at a rate of 4,57 USD per 1 head
